Name and Function

D/A

converter

(DAC)

DA0

DA1

Output Analog output: D/A converter analog output pins.

A/D

converter

D/A

converter

AVCC

Input

Analog reference voltage: The analog power

supply pin for the A/D converter and D/A converter.

When the A/D and D/A converters are not used, this

pin should be connected to the system power

supply (+5 V or +3 V).

AVref

Input

Analog reference voltage: The reference power

supply pin for the A/D converter and D/A converter.

When the A/D and D/A converters are not used, this

pin should be connected to the system power

supply (+5 V or +3 V).

AVSS

Input

Analog ground: The ground pin for the A/D

converter and D/A converter. This pin should be

connected to the system power supply (0 V).
